Efficient Certificate-based Encryption Scheme
|
Abstract:
The certificate-based encryption(CBE) is a new PKC paradigm which combines traditional public-key encryption(PKE) and identity based encryption(IBE) while preserving their features.CBE provides an efficient implicit certification mechanism for a PKI and allows a form of automatic certificate revocation,while it is not subjected to the private key escrow problem and secret key distribution problem inherent in IBE.This paper presented an efficient pairing-based CBE scheme and proved it to be IND-CBE-CCA secur...
